CASP3 and colon adenocarcinoma: For tumours with no or few corresponding normal tissue samples, such as lymphoid neoplasm, diffuse large B-cell lymphoma (DLBC), brain lower grade glioma (LGG), CASP3 as a negative expression of colon adenocarcinoma (COAD), and rectum adenocarcinoma (READ), we used normal tissue expression from the GTEx database added to GEPIA2 to analyse the results (Figures 1B,C).
